Blacked-out and built to work, the Weather Guard 114-5-04 wears a deep gloss black ARMOR TUF powder coat that matches modern dark trim and wheels. The wet-look shine wipes clean easily and stands up to sun, salt and jobsite abuse. Pair it with black wheels and dark trim for a clean, factory-blacked-out build that still shrugs off the weather. The deep, even shine photographs well too, which is a plus if you show or resell the truck. This full-size, extra-wide gull-wing crossover box mounts across the bed rails behind the cab and opens from either side through two independent lids, giving you 15.3ft³ of secured, weather-sealed storage. A five-piece welded aluminum diamond-plate body with a reinforced C-channel front keeps it strong yet light, and a full-perimeter D-shaped weather seal locks out rain and dust.
What's Included:
114 Series full-size extra-wide aluminum gull-wing crossover (cross) tool box in gloss black
Two independently locking gull-wing lids, 1Key UltraLock compatible, two keys
Under-rail mounting clamps and hardware for a no-drill install
Welded Aluminum Diamond-Plate Build A five-piece welded aluminum diamond-plate body with a reinforced C-channel front panel keeps this box strong yet light. It resists jobsite abuse and road salt without adding the weight of a steel box. This one is finished in gloss black ARMOR TUF powder coat.
Gloss Black ARMOR TUF Finish A deep gloss black ARMOR TUF powder coat gives the box a sleek, wet-look shine that pairs with blacked-out trim. The tough coating resists scratches, fading and corrosion so it keeps its finish for years.
Dual-Stage Rotary Latch, 1Key Compatible Each gull-wing lid uses an automotive-grade dual-stage rotary latch for smooth one-touch closing and solid break-in resistance, and the box is 1Key UltraLock compatible so you can key it into the same one-key system as your other Weather Guard boxes.
Full-Perimeter Weather Seal A memory-resistant D-shaped, multi-ridge weather strip runs the entire lid perimeter to keep rain, dust and debris off your tools, so your gear stays dry and ready in any weather.
Dual-Lid Gull-Wing Access Two independent gull-wing lids open from either side of the truck, so you can reach tools from whichever side you are standing on without walking around the bed. Each lid operates and locks on its own.
Crossover Fit With Bed Clearance The box suspends across the bed rails behind the cab and leaves room underneath, and a 12V access port supports lights and electrical add-ons. A removable divider tray helps organize smaller tools and hardware.
Reinforced Body, Automotive-Grade Hardware Weather Guard specifies a five-piece welded body for the 114-5-04, with a C-channel reinforced front panel and a heavy-duty C-channel reinforced lid, so the box stays square when it is loaded and when someone stands on the lid. The latch is an automotive dual-stage rotary mechanism, the same style a truck door uses, so it pulls the lid down onto the seal instead of relying on a friction catch. A welded gas strut shield keeps loose tools from knocking the strut mount out of line. The D-shaped ribbed weather strip is memory resistant, so it springs back after years of closing rather than taking a set and letting water track in.
Fit guidance: Crossover, or saddle, boxes mount across the truck bed on top of the two bed rails just behind the cab, so the box straddles the bed and leaves the bed floor open. At about 72" wide this size fits standard-width full-size pickups, and because it sits on the rails rather than the bed floor it works with short, standard and long beds on those trucks. This is an extra-wide box, so it needs a full-width full-size bed and will reduce side-to-side reach past the box. Always measure your bed rail width and check clearance behind the cab before ordering. It is not designed for compact or mid-size trucks.

Set the gull-wing box across the two bed rails behind the cab and center it left to right, then hook the included clamps under each bed rail and tighten the hardware evenly so the box sits flat and both lids seal. Because the box is wide and opens from both sides, have a second person help lift and hold it while you clamp it down. Follow the Weather Guard installation instructions for exact clamp placement and torque.

Use it alongside the printed instructions that ship with the box.
How the 1Key UltraLock System Works
A step-by-step look from Weather Guard at what the 1Key UltraLock actually does: how the cylinder accepts a new code, why the red push button retracts when the box is locked, and how the latch pulls the lid down against the seal. Worth two minutes before you set the box up.

Frequently Asked Questions
Straight answers on specs, fit and support
Will the 114-5-04 fit my truck?
It is a full-size extra-wide crossover, or saddle, box that mounts across the top bed rails behind the cab, so it fits full-size pickups such as the F-150, Silverado and Sierra 1500 through 3500, Ram 1500 through 3500, Tundra and Titan. It needs about 72" of rail-to-rail width. Measure your bed rails and check clearance behind the cab first, and note it is not designed for compact or mid-size trucks.
Does it require drilling to install?
No. The gull-wing box ships with under-rail clamps and hardware, so it mounts without drilling into your truck. Most installs take about 20 to 30 minutes and go easiest with two people to lift and hold the box while you clamp it down.
How does this gull-wing box lock?
Each of the two gull-wing lids has its own automotive-grade dual-stage rotary latch for smooth, secure closing, and the box is 1Key UltraLock compatible, so it can be keyed into the same one-key system as your other Weather Guard boxes. Two keys are included.
Does the gloss black finish hold up to sun and weather?
Yes. The gloss black ARMOR TUF powder coat is a hard, UV-stable and corrosion-resistant coating, and the full-perimeter D-shaped weather seal keeps the contents dry. It resists chips and fading through seasons of loading and road spray.
Will the gloss black finish scratch or show dust easily?
The gloss black ARMOR TUF powder coat is a hard, chip-resistant coating built for work trucks, so normal loading and unloading will not mar it easily. Like any glossy surface it can show fine dust, which wipes off with a quick pass of a microfiber cloth.
What is it made of and how big is it?
It is built from welded aluminum diamond plate with a gloss black ARMOR TUF powder coat. The exterior measures 72"L x 30"W x 19"H with 15.3ft³ of storage, and it ships at about 63.5 lb, so it is strong yet lighter than a comparable steel box.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
